A To all 'whom 'it may concern.'

well curb` -united to `ofFig. 4.

Be it knownthat I, CLIFFORD D. VoRIs, a citizen of the United States, residing at Crawfordsville, in the county of Montgomery and State of Indiana, have invented a newy and useful Corrugated-Metal Culvert,v of which the following is a specification.

This invention relates to sheet metal culverts of that general class especially designed for use beneath rail-way tracks, road ways and the like or in the construction of sewers,

and similar structures.

The object of the invention is to provide a corru ated sheet metal culvert formed of a plur 'ty of sections capable of bein readily ermit the formation of culverts of different engths and which may be quickly knocked down and the sections compactly nested for transportation or shipment.

A further object of the invention is to provide improved means for securing the culvert sections in assembled position, the fastening devices on the lon itudinal edge of one section Yforming a stop lor the longitudinal edge of the mating section, thereby to limit the contractile 4movement of said sections.

A still further object of the invention is generally to improve this class of devices so as to vincrease .their utility, durability and efficiency.Y

Further .ob'ects and advantages will appear in the ollowing description, it being understood that various changes in form,

proportions and minor details of construetion may be resorted to Within the scope of the ap ended claims.

In t e accompanying drawings forming a part of this specification: Figure 1 is a slde elevation of a knocked down culvert constructed inaccordance with my invention. Fig. 2 is an enlarged front elevation of one of the fastening devices. Fig. 3 is a vertical sectional view taken on the line 3,-3 of Fig. 2. Fig.v 4 is a front elevation illustrating a modified form of the invention. F ig. 5 isa top plan view of Fig. 4. Fig. 6 is alongitudinal sectional view taken on the lline 6-6 Similar numerals of reference indicatefcorresponding parts in all of the iigures of the drawings.

' The improved culvert forming the subject matter of the present invention com rises a plurality of tubular telescopic mem ers vof any desired length and each formed of mating sections 5 and 6 adapted to be assembled with their adjacent longitudinaledges overlap ed and detachably united so as to permit sal sections to be compactly nested for transportation or shipment. The sections 5 and 6 are stamped or otherwise formed with circumferential corrugations 7, the corrugations terminating short of the opposite ends of said sections to form terminal bearing collars 8.

Secured to the exterior Walls of each cul- `vert section at the over-lapped longitudinal ledges thereof are fastening devlces each preferably formed of interengaging members 9 and 10. The member 9 of the locking device comprises a substantially rectangular plate curved transversely toconform to the curvature ofthe exterior walls of the adja-l cent culvert section and to which it is secured by bolts, rivets or-similar fastening devices 11, said plate being provided with a depend ing shank 12 adapted to enter a socket or keeper 13 formed on the member 10 and provided with terminal threads for engagement with a clam ing nut 14. The member 10 is also prefere. ly concaved to conform to the exterior walls of the adjacent culvert section and is spaced inwardly from the longitudinal edge of said culvert section 6 so as to form a stop for the lon itudinal edge of the mating section 5, there y to limit the contractile movement of said sections. The up r section 5 is reinforced and strengthene at the member 9 by the provision of a plate .or Washer 15 which bears against the longitudinal edge of the section 6, -the lon itudinal edge of the section 5 being dispose in contactwith the upper longitudinal edge of the member 10 when the sections are assembled to'form a culvert, as before stated. It Will thus be seen that the clamping nuts 14 by engagement with the lower edges of tlie sockets 13 serve to lock the'sections .5 .and 6 in assembled position and prevent expansible movement of said sections, while the l0ngtudinal edges of the sections 5 and 6 by engagement with the plates 15 and upper .ed e ofthe member 10 serve to prevent contracte movement of said sections. Attention iS here called to the fact that by having the membersQ and 10 of the locking devices seated in the depressions or grooves formed between the corru ations 7, said fastening devices are effectue ly housed and protected.

Secured to the exterior surfaceot the e01- lar 8 of one of the tubular members is a socket adjacent longitudinal edges over-lapped, and

al fastening device independent o and semember 16 similar in construction to the member 10, there being a shank carrying member 17 similar to the member 9 and fastened to one of the corru ations of the adjacent tubular member wit its shank extending through the socket member 16 for securing the over-lapped ends of sald tubularmembers in engagement with each other when the clamping nuts 18 are adjusted. In bullding a culvert the sections compris' the tubular members are assembled witlinie adjacent edges ofthe tubular members 5 and 6 disposed in contact with themembers -10 and 15 and with the shanks of the membersV 17 extending through the socket 16, after which, the nuts 14 and 18 are adbolt or similar fastening device 20 so that by f justed thereby clamping the several sections in adjusted position. In order to knock down the culvert for transportation or ship- 'mentthe nuts 14 and 18 are removed and trated a modiied form of fastening device in v which each member of thefastening device is formed with a so cket 19 for the reception of a adjusting the nut 21 in engagement with the adjacent end of the socket on one of the .members the head 22l of the bolt will be forced in contact with the adjacent end of the socket on the other member thereby t0 clamp the culvert sections in assembled position. This form of fastening device is princi ally designed for fastening the overappe longitudlnal edges-of the culvert sections in assembled position and in order to conform to the exterior Walls of the culvert, the members comprising the fastening device are lpreferably concaved, as shown. If desired, owever, this form of fastening device may also be used for connecting the over-lapped collars 8 without departing from the spirit of the invention. It will also be understood that the tubular members forming the culvert may be each formed of a single piece of metal having its adjacent longitudinal edges overlapped and fastened by the locking device shown in Fig. 2 of the drawings instead of being formed in mating sections, without departing from the spirit of the invention. Havin thus described the invention what is claime is:

1. A culvert com rising a hollow section havin its adjacent ongitudinal edges overlappe and co-actingfastening devices independent of and secured to the over-lapped portions of said section and bearing against the' adjacent longitudinal edges thereof for limiting` the expansible and contractile movement of said sections.

2. A culvert comprisin a hollow section corrugated circumferentia y and having its and fastening devices independent of an se'-` cured to the exterior-walls of said section at aging members,

4. A culvert comprising a hollow' section corrugated circumferentially and having its vadj acent longitudinal edges over-lappedZ and spaced interengaging fastening devices independent of and secured to the exterior walls of the, culvert section between the corrugations and serving to limit the expansible and contractile movement of said culvert. sections.

5. A culvert comprisin a hollow section corrugated circumferentiar y and having its adjacent longitudinal edges over-lapped, plates secured to the over-lapped edges of pro- Orf' plate provided wit a said` section, one of said plates being .vided with a shank having a threade tion and the other socket for the reception of the shank, and a nut engaging the threads on the shank and bearing against the adjacent end of the socket.

6. A culvert comprising a pluralit of telescopic'members each includin a ho ow section corrugated circumferentisilly and having its adjacent longitudinal edges over-lapped', a locking member secured to one of the overlapped edges of each section and provided with a threaded shank, a co-acting locking member secured to the other over-lapped longitudinal edge and provided with a socket or the reception of said shank, a late secured to the interior wallsof the.c vert and bearing against and forming a st'op for one of said longitudinal edges, the other longitudinal edge being disposed in contact with the socket, and nuts engaging the threads on the shanks for locking the over-lapped edges of the sections in assembled position. V

7. A culvert comprisin a plural'ty of telescop1c`members each inc uding mating sections corrugated circumferentially and having their adjacent longitudinal edges overlapped, fastening devices secured tothe longitudinal edges of one section of each tubuar e member and provided with threaded shanks, co-acting fastening devices secured to the longitudinal edges of the mating sec- A tions and provided with sockets for the recollar adapted to over-lap the bearing collar of an adjacent' tubular member, a fastenin device secured to the exterior Walls of one o the members and provided with a threaded shank, a fastening device `secured to the bearing collar ofthe mating tubular member and having a socketformed therein for the reception of the shank, and clampin nuts engaging the threads on the sha s for clampmglsaid bearing collars in engagement with eac y 9. A culvert including ahollow sectlon other.
